- INKING MECHANISM FOR r t nrm'srnn'ssnsy To all whom it mag "concern Be it known that I, J OHN H. Sormu, a citizen of the United States, and resid ng at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in, I'nki-ng Mechanism for Printing-Presses, of which the following is a specification, such as will enable those skillediin the art to which, it

a ppertains to make and use the same.

This invention relates to printingpresses, and particularly to what areknown as b printing presses, and inv its practicalfappliw cation, the invention relatesparticularly to inking mechanism for presses of this'class;

, and the object thereof is to provide a press of this class having. afla-t rectangular-inking table and, the usual table inking rollers which operate in connection with said table, and by means of which the ink is applied to said'table with my improved inking mechanism, whereby, the printing in parallel rows of difierent colors may be produced at one operation; and withthis and other objects in View the invention consists in an inking mechanism for purposes of theclass specified, constructed andv'operating herein-v after described and claimed. a

The invention-is; fully disclosed in the following specification of which the accompanying drawings form a part, in which the separate parts of my improvement aredesignated by suitable reference' characters, in each of the views, and in which;

Figure l is a plan View of a part ofa job printing press provided with my improvementg Fig. 2a side view thereofi Fig; 3 a longitudinal vertical section onfthe line 33 of Fig. 1 Fig. 4: a transversevertical section on the line of Fig. 3, and ;Fig. 5 a similar section on the "line 55 of Fig. 3a v y I In the-accompanying drawings I have shown only such parts as are necessary to illustrate my invention, the printingiorm or form rollers or platen and theform; ink-1 ing roller or rollers by which the ink is taken from the inking table and applied to the form roller or platen being nowl shown. f

In said drawings I have shown at athe inking table, and at b, c and alparts of the SpecificationoflettersPatent. Patented Qgt;20;1914 Applicationfi1edAugi st5;1313. seriailnarsaoaa.

frani'e which i support the usual 1 mechanism in the printing parts ofthis' ma 1 chine, said partsconsisting,inthe construc U011" shown, of upr ght members, and Ihave' also shown, at'e another'part of said frame 7 with which the table a is connected.

Moullted in jthe top ofthepartfc oft-the i frameis a main inking roller f, and in the l K top of .the part a vsuppl'ernental inking v roller 9, and the inking roller 7"; consists of afcentra lshai'tfwhioliflis angular" infcr'oss sect onandon' which-is mountedf a plurality of inking disksjf?'which' 'are three'in number, in the construction shown,

and these inking rollers are spacedby means which are mounted a plurality {of "inking disks 9 which, iii the, construction shown,

are three number, andthese inkingdisks are jalso "spaced by collars or sleevesgfiand 1 p in the use of my improvement, the distance between the inking disks f and'zfthje' inking disks g' 'maybe increased ordecreasedbyemploying longer or sholterspacing coll v or sleeves, as will be readily understood; i

The shaft f ofzthe m in inkingroller is provided at one end with a projecting trunnion f on hwhicli is mounted .a gear f 1 c and onfwhich i also mounted'a'cam tas s I provided with'la peripheral groove i and mounted above and atth e back' 'oftheinking'roller f are finkspreading rollersh and 11 mounted on shafts i24 and h pro vided at one endwith trunnions 71 and Jo A the cam disk f and by means ofithisicon? 'andthese-ltrunnions areprovided with pins o k andfh which move in the groove f? of T v I i struction the ink spreadingv rollers and 71,, I in the operation of, the machine, are given r:

a longitudinal oscillating orvibratory movement, this result being efl'ectedsbyfreason of,

the fact that the; rollers 71, and fh 'larefrotata'bly mountedon the shafts h la nd h an d also move longitudinally with said shaft, I

andthisresult may be accomplished by'pro-f";

viding I the} shafts it and {7& with stoppins 71 at the endsofthe rollers k and 71 1 v Mounted gin l front of the supplemental.

[main ink roller g are two ink spreading rollers 2' and 2' which correspond with the ink spreading rollers 7t and k and which are constructed and operated in the same manner as said rollers h and if, the supplemental main ink roller 9, or the shaft 9 thereof being provided at one end with a trunnion g on which is mounted a gear 9 and a cam disk 9 provided with a peripheral groove 9 and the ink spreading rollers v same as that of the ink fountain i while the font y' has a forward and backward movement and takes the ink from the roller 7' and applies it to the disks f on the main ink roller f, this construction being old and well known. Beneath the main ink roller f are other font rollers 76 and 70 and the font roller it operates in the usual manner in the font it and the roller ic has a forward and backward movement and takes the ink from the roller is and applies it to the disk g of the roller g'.

@In the accompanying drawings 1 have shown at m and m the table inking rollers whichare mounted in the usual manner in the carriage m and movable forwardly and backwardly over the table a, and said car- 'riage is provided at both sides with link members mfiwhich connect with corresponding link members at, and in practice, the link members m areconnected with the form inking rollers, not shown, and by which the ink is applied to the printing form or platen, alsonot shown. The rollers m and m are vertically movable in the carriage 1123, but the constructionfland operation of the parts m, m m m and wa being the same as in other machines of this class.

The table a isprovided with the usual backwardly directed arms a, and directly over the supplemental main ink roller 9 these" arms are provided with raised tracks m and in the operation of the machine the carriage m and rollers m mountedthereon, move back and forth over the arms a as well as over the-table a, and in Fig. 3. of the accompanying drawings, the rollers m and the carriage m are shown in their rearmost position in full lines, and in their foremost position in dotted lines. In the above described operation, the roller m rides up over the tracks or ways a and does not come in contact with the supplement inking roller 9, but does come in contact with the main inking roller This result being accom plished by means of small track rollers m mounted on the trunnions of the roller m and which ride over the tracks or ways of.

The table inking rollers 77?. each apply one color to the table a, and as shown, the front roller m applies blue ink and the roller m, red, and in Fig. 1 of the drawings, I have indicated blue ink at m and red ink at and it .will be understood from Fig. 3 of the drawings, that the roller f applies the red ink to the-roller m, and the rollerg the blue inkto the roller m Mounted in the part 0 of the frame is the usual drive shaft 0 provided with; a pinion 0? which meshes with the gears f and g on the trunnions f and g of the shafts f and g and by means of this construction the rollers f and g are given a rotary movement. The parts 0 and cl of the frame are each provided at one side thereof with detachable members 0 and d whichpermit of the adjusting of the disks f and g on the shafts f? and 9 or the insertion or the interchanging of disks ofvarious widths which will be determined by'the operator.

In the operation of this machine, the rollers f and g are given a rotary movement, the table inking rollers m and m are moved forwardly and backwardly over said table, and said rollers and the fountain rollers i and are moved forwardly and backwardly, all this being accomplished by the usual operation of the machine, but with my construction instead of applying one color of ink to the table a, I apply different colors in parallel lines, and althoughI have shown the colors applied to the table in lines of the same width, it will be understood that the width of each of'these lines and the number ofsaid lines will be determined by the disks f and 9 as hereinbefore described.

My invention is not limited to any exact construction for the table ink applying rollers m and 112?, and these rollers may be constructed in the same manner as the rollers f and 9, if desired, and changes in and modifications of the other features of construction herein shown and described may be made, within the scope of the appended claim, without departing from the spirit of my invention or sacrificing its advantages.

Having fully described my invention what I claim as new and desire to secure by Letters Patent is A printing press having two main inking rollers each of which is provided with a plurality of spaced inking disks, an inking table in front of said rollers and provided with tracks or ways which extend backwardly thereover, a carriage movable over said table and over said tracks or ways and provided with two ink'applying rollers adapted to operate in connection with the main inking rollers and to apply ink to said table, and

means whereby when the carriage moves presence Of the subseribingwitnesses this backwardly over the inking rollers, one of 2nd day of August 1913. the ink applying rollers in said carriage will be raised above the frontof the main inking Y EU? I 5 rollers. Witnesses: In testimony that I claim the foregoing as k i S. 'ANDR Ws,

my invention I have signed my name in O.-'MULREANY.
